Uniden PRO340XL is a powerful handheld CB radio that operates on any of the 40 AM frequencies authorized by the FCC. It features superheterodyne circuitry for enhanced receiver quality, and Phase Locked Loop Synthesizer techniques to assure precise frequency control. The PRO340XL can be powered by 8 AA alkaline batteries, 10 rechargeable AA nickel-cadmium batteries, or from your vehicle battery. It also has a connection for an optional nickel-cadmium battery charger.

Introduction

Welcome to the world of CB radio communication. Your Uniden

PRO340XL

represents the most advanced portable radio ever designed for use in the

Citizens Band Radio Service. This powerful unit operates on any of the 40 AM

frequencies authorized by the Federal Communications Commission (FCC).

Among its many features, the

PRO340XL

includes:

•

Superheterodyne circuitry

to enhance receiver quality.

•

Phase Locked Loop Synthesizer

techniques to assure precise

frequency control.

• Flexible operation that allows you to power the radio with 8 AA alkaline

batteries, 10 rechargeable AA nickel-cadmium batteries (batteries not

included), or from your vehicle battery.

• Connection for an optional nickel-cadmium battery charger.

This radio has been type accepted and fully certified by the FCC.

WARNING

The Citizens Band (CB) Radio Service is under the jurisdiction of the

Federal Communications Commission (FCC). Any adjustments or

alterations which alter the performance of the transceiver’s original FCC

type acceptance, or change the frequency determining method, are

strictly prohibited. Replacement or substitution of crystals, transistors,

ICs regulator diodes, or any other part of a unique nature, with parts other

than those recommended by Uniden may cause violations of the technical

regulations of Part 95 of the FCC rules or violation as type acceptance

requirements of Part 2 of the rules.

Elimination Of Licensing

The Federal Communications Commission has ruled that Citizens Band Radio

Service operators are no longer required to obtain an FCC license to operate

their CB equipment. In doing so, the FCC also permits CB stations to operate

without station identification.

Elimination of individual station licenses results in no lessening of the operating

privileges or responsibilities of CB users. An operator of a CB radio station is

still required to comply with the Communications Act and with the rules of CB

Radio Service.

be supplied through 10 AA, 1.2 volt, rechargeable nickel-cadmium batteries; 8 AA,

1.5 volt alkaline batteries; or through the supplied cigarette lighter power cord when

connected to a vehicle’s 12 volt negative ground power system.

Installing Batteries

WARNING: Do not mix alkaline batteries with nickel-cadmium batteries.

Alkaline Batteries

Note:

To insure circuit continuity, use the two battery spacers supplied.

1. Slide the cover off the back of the

PRO340XL

2. Insert the battery spacers in the positions shown. They should go all the

way into the case.

3. Insert 8 alkaline batteries into the compartment as shown.

Note:

Be sure to insert each battery with the proper polarity, as marked in

the battery compartment.

Follow this diagram for correct alkaline battery placement.

4. Replace the cover.

Note:

When the batteries become weak, the BATT LOW LED will light.

Be sure to replace the batteries as soon as possible. You can

preserve battery power by selecting the “LOW” position on the

HI/LOW switch. The “LOW” setting has a substantially shorter

transmission range. (See the Operation section.)

Battery

Spacers

Nickel-Cadmium Batteries.

1. Slide the cover off the back of the

PRO340XL

2. Insert 10 nickel cadmium batteries in the compartment.

Note:

Be sure to insert each battery with the proper polarity, as marked in

the battery compartment.

Note:

The battery spacers are NOT used when installing nickel-cadmium

batteries.

Follow this diagram for correct nickel-cadmium battery placement.

3. Replace the cover.

Note:

When the batteries become weak, the BATT LOW LED will light.

Be sure to replace the batteries as soon as possible. You can

preserve battery power by selecting the “LOW” position on the

HI/LOW switch. The “LOW” setting has a substantially shorter

transmission range. (See the Operation section.)

Connecting the Cigarette Lighter Power Cord

Using the Cigarette Lighter Power Cord whenever you are operating the

PRO340XL

in a vehicle saves the radio’s internal battery life.

IMPORTANT:

The Cigarette Lighter Power Cord is designed to be used

ONLY

with

negative

ground vehicles.

Do not

attempt to

operate the unit with the power cord connected to a positive

ground vehicle.

To connect the Cigarette Lighter Power Cord:

1. Connect the power cord to the

POWER

connection on the side of the

radio.

2. Plug the power cord into the cigarette lighter of your vehicle.

Note:

Power is disconnected from the radio’s battery compartment when

using the cigarette lighter power cord.

Operation

Before operating the

PRO340XL:

1. Be sure you read and understand Part 95 of the FCC Rules and

Regulations.

2. Be sure that the power source and antenna are properly connected.

3. Turn the unit on by sliding the power switch up to the ON position.

Receive

1. Use the

Up/Down

channel keys to select any of the 40 channels. Press

once to change one channel at a time. Press and hold to rapidly change

channels.

2. Set the

VOLUME

control to a comfortable listening level.

3. Adjust the

SQUELCH

control to eliminate background noise during the

absence of a signal. Move

SQUELCH

to the right

until the noise

disappears (no signal should be present). Leave the control at this

setting. The receiver will remain quiet until a signal is actually received.

Note:

Do not advance the control too far, or some weaker signals will not

be heard.

Transmit

1. Set the

HI/LOW

Switch.

• In the “HI” (4 watt) position, the unit transmits at maximum output power

and achieves maximum range.

• In the “LOW” (1 watt) position, transmission output power (range) is

substantially reduced; but, the battery life will be increased.

For maximum battery life

select the “LOW” position. This switch does

not affect the reception range.

2. If the channel is clear, press the

Push-To-Talk Button

on the side of the unit.

Be sure to speak clearly into the microphone.

IMPORTANT:

All channels, except channel 9, may be used for normal

communication. Channel 9 is reserved by the FCC for emergency

communications involving the immediate safety of individuals or the

protection of property. Channel 9 may also be used to render assistance

to a motorist.

This is an FCC rule and applies to all operators of CB

radios.

Care and Maintenance

The

PRO340XL

is designed to give you years of trouble-free service. There are

no user-serviceable parts inside and except for the batteries, or the fuse inside

the cigarette lighter plug, no maintenance is required.

Note:

Do not expose the unit to moisture. Rain, dew, road splash, or

other liquids may damage the internal components.

Replacing the Cigarette Lighter Plug Fuse

The cigarette lighter plug contains a 2-ampere fuse to protect it from power surges.

To replace a blown fuse:

1. Squeeze the two metal contacts on the cigarette lighter plug cap and

unscrew the cap counterclockwise.

2. Remove the fuse and replace it with the same type.

3. Replace the cap by grasping the plug’s two metal contacts and squeezing

them while twisting the cap back on. Make sure the cap is tightly secured.

Replacing the Batteries

See “Installing Batteries.”

Recharging Batteries

You can recharge nickel-cadmium batteries while they are installed in the

PRO340XL

Adapter (AD140U). Be sure to observe the polarity of the Adapter before

connecting it to the radio.

Note:

The

PRO340XL

will not operate while the batteries are recharging.

WARNING

Do not attempt to charge alkaline batteries in this radio. Make sure you

have installed 10 rechargeable nickel-cadmium batteries before

connecting power to the charge connection.

Using the Cigarette Lighter Power Cord

IMPORTANT:
